Installing a Nest power adapter

[Pjandrada]

Hello,

I'm trying to install a Nest thermostat and fund out tha I need a nest power adapter. I got it and now I'm trying to hook it to my heater controller board.

1- it's a heat only system (Thermolec on demand whater heating system)

2- My old thermostat had only two wires connected.

3- on the controller board there's different connectors from what is showing on the nest manual.( S,S2,W1,C,B,B,OT,OT)

4- Two wires connected ( W1,C) 

5- S1,S2 are with a jump 

 I would really appreciate if I could get some help with this since the letters for the connectors are different I'm not sure on how to do.
